An Ecolab vice president based out of St. Paul is among the passengers not immediately accounted for in Tuesday night's Amtrak train crash.

Robert Gildersleeve, 45, was on a business trip at the time. Gildersleeve is a vice president for corporate accounts for Ecolab's institutional business.

"We are concerned about Bob's well-being and are hoping for the best," said Roman Blahoski, a spokesman for the St. Paul-headquartered company.

Gildersleeve has worked for Ecolab for 22 years and lives near Baltimore, Blahoski said.

Gildersleeve's family was in Philadelphia, circulating his photo and information about what he was wearing. He had a ticket for the train that crashed Tuesday, his father said, and relatives have been unable to get information from Amtrak on his whereabouts.

Gildersleeve is married and has two children, ages 16 and 13. The younger son was in Philadelphia with his grandfather to look for him.
